Deploy Workflow via Eclipse

I am trying to deploy workflow with processimage.jpg (to be visible in Alfresco later). The problem I have my own content type and if I am deploying via Eclipse, am I getting org.alfresco.service.namespace.NamespaceException: Namespace prefix ttf is not mapped to a namespace URIWhere I have to put c

Here are some comment, maybe useful for others.

About content type - after adding it directly to shared folder I was able to deploy via Eclipse, but… still no image.
Fist of all its strange that there is no possibility to add the image directly, because even if could deploy via Eclipse, the image almost is useless as such things as jbpm objects "join", "transition", etc are useless for average user. I just wonder how the others are explaining to users what this image means.

Instead of trying to find the reason for "deployed but not visible" I just decided to rewrite this part.
First of all, method what returns the link to image is in file
ManageTaskDialog.java:
public String getWorkflowDefinitionImageUrl() {
return "/workflowdefinitionimage/" + this.getWorkflowInstance().definition.id;
}
As didnt wanted to recompile this class I started to investigate where is "/workflowdefinitionimage/".
And "/workflowdefinitionimage/" is implemented as servlet WorkflowDefinitionImageServlet.java.
So this file can be modified, in my modification I just created new directory in images where I put workflow image and modified servlet that it loads this file. Later I will implement images in form workflow_name_task_name.jpg to be able mark the current task or even implement runtime task "marking".

Thanks.

Hmm … lets take it back for a moment.

a) When you deploy via eclipse, the connection test ist "Succesfull" and the deployment ok, the JPG, you see in eclipse, is automatically transmitted as well. You do not have to do anthing else to do that.
b) After deployment, you have to make your, the workflow and the image are integrated in the gui. For both, you need to edit extra XML files, see the Wiki for details on that
c) The jpg is a "hack", not officially supported.
d) You can rename all the components and maybe even hide the classification strings like <<join>>, <<Task-node>> etc. But I think, for most endusers, the display is mostly belly stroking, since it is static and sometime hard to understand, if you do not know your workflow stuff

So, given you did all the above correctly, what do you need additionally ? I could not quite follow.

Hi,
I only know this here from the wiki http://wiki.alfresco.com/wiki/WorkflowAdministration#Display_of_Workflow_Definition_Diagrams

I did not try it out, but I know it was there back when I started with 2.9 Labs. So it might not work anymore due to version problems.
